:SAILING-PRESS.

To all lwhom it may concern:

Be it. known that I, THOMAS J. CORNING,

lcitizen of thel United States, residing at Orion, in the county of Henry and State of plllinois, have invented certa-innew and useful Improvements in Baling-Presses; and I do hereby declare that the following is a full, clear, and exact description of the inlight form ofy power for its operation.

A further object is to construct a baling press in which-the power is made to impart a. progressive step-bystep movement to the plunger.

A further object is to construct a baling press in which the operating power will be cumulative in that between'each step-by-step movement imparted to the plunger said power will be automatically freed from the plunger andy revolved to gain momentum before again imparting its movement.

A further object is to simplify the con struction of baling presses generally so that but a very small driving power Will be required in the operation of the same and depend considerably upon the momentum of balance wheels.

Further objects will appear as the following specification proceeds.

In the appended drawings, Figure l is a side elevation of my improved baling press. Fig. 2 is a top view of the same. Fig. 3 is a horizontal section of a part of a press showing part of the plunger. Fig. et is a longitudinal section of the main portion ofthe press on .amuch larger scale than that of the rst two figures. Fig. 5 is an end elevation in `partv section of the press as viewed from its rear end. Fig. ,G is a longitudinal section of a spring plunger and its case. Fig. '7 is a perspective view of a reversible hopper. and Fig. 8 is a view of certain portions of Fig. 4 shown in ditl'erent positions from? those of said figure. y Y j The body of the press is preferably con-g structed of what is known as angle iron 7 and channel iron, readily found in the lopen market and whichl makesa compaia,

tlvely cheap and thoroughly ricrid frame.

members by means of vertical stays or braces B and B, also of angle iron, as shown inf( Fig. 1, the forward extremities of the bars' A being provided with. the usual upright threaded bars C having the hand wheels'DV by which to contract the space between the upper and lower parts of the frame, this being common to most machines of this class.

The bottom and top of the press are suitably `covered with. sheet iron as 1indicated by E. c

Extending between and having' their ends secured to themembers B are..t 7o channeled members G, the flat sid which form the walls of the usual co'i'ore'ssio'n chamber indicated at H in Fig. 2. In the top of the machine is an opening J, and mounted above and surrounding the. opening is a hopper K open.'on one of its sides and provided with a chute L, the latter being removably attachedl to the hopper in any suitable manner and liaving supporting legs Mwhose free extre fes rest upon some convenient part of thev e. This chute is used in order that the 'hay or. straw may be placed thereon and afterward dragged into the hopper by the operator thus saving loss of the materialin transit from the source of supply to the'hopper and provides a convenient resting place for it until wanted.

N indicates the plunger corresponding to that used in nearly all presses, and ay part of this is shown in horizontal section in Fig. 3, the rear s'ide having attached thereto suitable vertically disposed angle bars O, Figs. 3 and 5, to each of which is rigidly secured a. toothed rack P corresponding to the pit man :usually employed. Beneath the racks just mentioned is a horizontal shaft Q, suitably jo1nnaled in the frame, which carries a heel R positioned between the two $11.111?. e raclsresgribed. This wheel is provided y"with two-studs S and S', at each side, which are providedwith friction rollers T and T respectively. These rollers are provided for imparting ,longitudinal movement to the racks, or pitman, for the purpose of imparting movementto the plunger N for compressing the hay or straw being baled.

At U is a driving shaft to which the power ,is connected in any good manner,-and whichvis provided with a pinion Vand the tion roller T of the stud ends of the shaft outside the machine carry balance or iy wheels W. Revolution of the pinion imparts movement to the Spur gear with which it isVv in engagement, thereby imparting an orbital movement to the studs S and S and their rollers.

It will be noted in Fi 4 that the fricis inl engagement with one of the teeth of the racks or pitman. Movement of the stud toward theY left will start the pitmanV forward. Asthe roller completes its movement in an'arc and is about to leave the tooth the roller T will rhavecome into position to engage the suc- Xeeding toothto continue the movement of t \e pitman and carry it a distance equal to y, that imparted to it by the first roller.

Carried by the plunger, at eachside, is an arm 2, one of which is shown in Fig. 3, each Vzo of which extends horizontally from said plunger through a slot orA opening 3 created by slightly separating thevcliannel members Y G hereinbefore described as clearly shown in Fig. 1. Theo'uter extremity of each arm 2 carries a'dog 4 free to swing thereon. Se-

- litlowermost of the members G at each side of the machine is a bracket 5 having` a horizontal extension in which, as

cured to ft shown in Figs. 2 and 8, are two apertures 6 in line with tlie'dogs 4 which drag over said bracket. As the plunger is given its movement by the means described and the friction roller T is about to leave the teeth of the pitman the dogs 4 at each side drop into the said apertures 6 as indicated in Fig. 8. In this figure is clearl 'shown the position of Vthe teeth ofA the rac r or pitman with regard Y* movement due to the hay under compression.

Once more the rollers leave thelteethl'and then engage lsucceeding ones andicarry the plunger forward for the final act of compression. j. I

Secured in a suitable jmannertoopposite sides of the press, behind the? er, are twocylindrical spring-cases l'wir in y each of which is a compression-,springS through which passes a rod 9 one end of which extends through the case ,7 'and' has connection with the plunger b means-of a chain 10. VThe op osite end o the rodear ries a plunger- 11 fior receiving the rear`end `of the spring, through which the 'rofd' eirtends, lthe rear end ofthe latter having an adjusting nut vor similar device 12 by which to obtain any degree of compressure of'theY spring. At the time the plunger N starts forward for theinal compression the slack inthe chain, indicated in Fig. 4, is taken u andv the spring is then put under more an more compression as the plunger reaches its limit of movement. When the roller T has once more released the tooth` with which it was in engagement the rack is liberated and the spring' returns the plunger to itsnormal or starting position. Y v

Atthe rear end of the press and suitably mounted upon a member F of the frame areV two bent arms 13 each having near their rear ends aninward bend as at 14. Extending through the free ends of the arms is a rod 15 on which is a sleeve 16 lying between the arms 'for limiting the movement of the latter toward one another.v 'lhe free ends of the rod carry adjusting nuts 17 and between these and the arms 13 is a compression spring 18. The rear ends of the racks P which form the pitman are rigidly connected as by a member19 and the sides of the racks are grooved orrecessed at 20 to receive the inward bends 14 of the said armsV 13. The distance between the said arms as held by the springs. 18` is less than 'the width of 'the pitman and as the latter is returned to the starting position through the medium of the springs 8, before described, the pitman enters between the arms 13 to separate them, said arms acting asa bumper to absorb the shock. As the arms are s read the pitman enters between them an the bends 14 of the arms enter the recesses 20. By this means the arms besides acting'as a bumper as described, also hold the .pitman andpi'event any tendency to a back-lash In addition to this I may employ rubber bumpers G, or equivalent means, between the members G, for example, as shown in Fig. 1, to receive the impact ofthe arms 2 in the return movement.

Anymeans may be used, ifneeded, to hold the pitman in its pro er working position, its weight, however, ing suliicient to prevent it' from rising from its horizontal position. In order to prevent it from falling below said horizontal rposition and that it will'have proper relation with regard Yto the friction rollers, I mount a guide at each side thereof as indicated at 21, the rear ends of which are suitablyrsecured tothe member F, the means, however, not being shown. The forward ends of said. guides are hung from the sides of the machine by supporting links 22, Fig. 5. Near and upon the rear end of each rack of the pitman isl secured a plate 23 which projects at each side thereofand rests upon the said uides and slides therealong, this being .rea ily understood by a study of Fig. 5. 1

The vplunger is provided with an upwardly and rearwardly extending. hood 24 which, as the plunger moves forward, is car- Varied beneath the. harper.. teclas@ the; eren' ngJ Ain Order t'. Prevent-hey-f-'gettg belhind the plunger and into the working parts@ w-whenthe latter ispassingbeneath the said `opening. ,Butthis isconi'mon-to most; bal-` ing presses. In connection withthis hood I Vplace a number of fixed teeth at one endi of the opening Jand constituting what mayv -be termed a combf which extends into the throat or opening of the hopper in substantially the position-shown and pointing vtoward the rear or plunger-end of the press. The main duty of this comb as vI use it is to thin down or separate excessive charges of hay, making thecharges as finally pressed into the bale of a uniform size.' The use of this device becomes essential in a press that does not contemplate the use of a selfffeederj It acts to comb or shred and separate each: Y'charge of hay. Ifit were not for this de? vice a large mat, or chunk, or lump of hayv might be forced in ahead of the plunger.. But the"co'm b dividesv it Vand makes the charges of uniform size.

.At 26is` a folder-for assisting in doubling fthe hay back and forth, but this is also common to baling presses and consequently noth- ,ing new is 'claimed in connection therewith.`

The hopper K is preferably detachablev and reversible and the means by which this vis accomplished is clearly shown in F ig. 7. A vertical flange 27 is bolted to the top of the press to surround the opening J and this said flange carries a series of'bolts 28. The hopper is designed to snugly 'fit within this flange and is provided at its-bottom edges with slots 29 corresponding with and forreceiving said series of bolts. By loosening said bolts, the hopper can be removed and reversed in position so that its opening maybe positioned at the opposite side of the machine the hopper being replaced in the flange the slots coming opposite the position of the bol'tsso as to receive them. Any de-A sired manner of detachahly securing the chute-L 'to thehopperl may be used, it being preferable to do this by frictional engage-j ment, however, so -that there will be no parts to adjust or become lost.

It will -have `been understood from the lforegoing that the main object of my inven- 'tion is. to construct a bailing press that will Irequirebu't'a very small or "light form of power forl its operation. Contrary to most Lof the baling presses of which I am aware f-I gainpowerfthrough the use -ofbut.v three elements, viz :.the-spur gear R, the pinion P va-n d1 t he{s tudswS and S; providing two heavy :jj-,b alance-whefels fo'rthe driving shaft, the purpose of -whichwill be understood presa entl'y. I 'am enabled to use an engine or ot her source ofpowerof'but two or threev 'hforse 1 .p ower since-,as I construct the ma- ?.elliieef tleffeeerne-.runsentirely free and aaithsatileae etrteie interva1.s;,se that@the -ialvemelltef-the plungerj As has `beenstated, the friction rollers T `a system of gearing comprising but parts makes the press very low 1n cost of balance; Q1?V l.fly wheels, can, ,gain espe-@f1 .by which to store power and u tllizethe momentum as .part ety thel pcwelty for a Sueeeedine A andfl give the initial movement tothel" plunger and .at the end of that movement the plunger is lheldstationary by the dogs 4,' the entire gearingv then being liberated to gain speed.` Xsthe speed of the drive'shaft U is .very-I high the fly .wheels are sufficiently" .heavy to carry the plunger forward against 4the hay at the next movementaided, of course, by the power itself. The pinionsare .very small as compared with the size of the.v

spur gear R so that the power is given ample j time 1n which' to recover after eachmovement imparted to the said plunger. Ifvthe movement of the plunger were a continuous 'or unremitting one the power would be necessarily greatly decreased, but .an interf' mittent movement permits the use of avery small power as compared rwith thatusually required. i

A power deviceof smallhorse power, tindk manufacture and also makesit more -easily portable by reason of its lightness.

`I do'not, of course, confine vmyself to the` particular arrangement of the parts shown` herein, since equivalent constructions may be used- Vwhile accomplishing the object sought. I'have not dwelt upon the manner lin-which the bales are started and formedv and compressed since this is well understood.

In effect, the toothed pitman and the frictionfrollers constitute a rack and mutilated pinion, the said rollers corresponding to two teeth of such a form of pinion. The gear R,

orpinions of this type for the purpose intended. It may be observed that I am not .necessarily confined to the use of two rollers,

or teeth, since one could be used, or even more than two could likewise be used. In one case the plunger wouldv have more movements but shorter ones, and in the other case the plunger would have fewer movements and longer onesunless the distance between the teeth of the rackand the distance be-4 tween the rollers were changed tosuit the length of the compression chamber.

Having thus described my invention, I

claim .engage Said Pitman at eahrevoluten. there therefore, or its shaft, could carry a pinion of to impart a series of progressive movements to the plunger.
